Application ffled May 11, 1928. Serial No. 277,062.

This invention relates to llliPlOVQInGfli'S in separators, particularlyto a sand and stone or rock separator, and it is the principal object ofmy invention to provide aniotor operatedseparator of this type in whichthe material scooped from the ground is broken up within a hopper andthen transferred to a screen and sifted therein, whereby provisions aremade to remove the rocks and stones'not passing through the sieve orscreen during the sitting operation at the end of each operation. p i

Another object of my invention is theprovision of a sand andstoneseparator in which the screen is submitted toashaking motion andthe screen. of which allows a lowering of its rear part to deliverlarger bodies not passing the screen meshes to ashuttlc or chuto forremoval.

A further object or rnyinvention is an provision of a motor operatedsand and roe;

separator equipped with novel and improved steering and braking means. Astill further object of nryinvention is the provision of a motoroperated sitter for sand and. gravel etc. of comparatively siniple andinexpensive construct-ion yet officient in operation.

These and other objects and advantages of my invention will become morefully known as the description thereoi proceeds, and will then hespecifically defined in the appended claims. I

As illustrated, the separator comprises a box 10, supported on a framellcarrying the axle l2 tor the larger rear wheels 13 and the axle 1liior' thesinaller front wheels 15.

On one side the frame carries a seat 16 for the operator with which afoot rest 17 is combined, while uuoer the seat a tool box or chest 18;and beside the drivers seat a switch box 19 are provided. I

A scoop 20 has its operating bars 21 pivotallysocured, as at 22 to frame11 and formed into toothed segments 23, in mesh with gears 2% on a shaft25, which also carries a pulley over which a belt 27 runs which is alsoguided over-a pulley 28 on a shaft 29.

A chute or hopper 30 is arranged at the ftront end of box 10 and adaptedto receive the material from scoop 20; The bottom of the chute is openand can be closed partially or entirely by means oi": the chsplaceableside "wall 31 which carries a rack on its outside in mesh with a gear 33on a shaft-3 L which carries a hand wheel 35 at its outer end Fig. 7 1lVithin the hopper a longitudinally extending shalt 36 is join-nailedwhich carries a plurality of stirrer blades 37 arranged in spacedjuxtaposition within the hopper 30.

The shaft 36 carries outside of the hopper a pulley 38 over which a belt39 is guided and also over a pulley on a transverse shaft 4L0.

An endless belt ll having a plurality of frames 42 on its upper face isguided over a pulley d3 on shaft 40 which carries also a pulley a l overwhich a belt 45 is guided, which is also guided over a pulley 46 onshaft 36 to operate the stirrer within the hopper.

, The belt 41 is also guided over a pulley 47 on a shaft is ournalled insuitable bearings on the box id Suitable guides i9 are proared. atcertain intervals and/suitably arranged to hold the belt taut. I

"lhe box 10 in its rear parthas a depending body '50 attached to itsbottoinpart and above the some a screen Si is suspended at its rear endby means of cables 52 guided over suitable rollers 53 on a shaft 5i. Tothe front part or end wall of the screen an extension 55 is attachedwhich rests on a roller 56. Anni-m 57 is attached at one end'to an eyeon the end wall of the screen andat its opposite end to a link 5.8 theother end of which iseccentrically secured tothe' side face of aintermediate the ends of a rod 99 adapted to be i 101.

: tached as bar 118 articulated, as at 119, 120 to axle 14.

tion, andthe shaft 54 carries outsideof the box 10 a hand wheel 65,while a ratchet wheel 66 on said shaft is engaged by a pawl 67.

On a transversely arranged beam 68, a motor 69 is located, the shaft70of which carries a gear 71 mesh with a large gear .72 on a shaft 73which carries alsoa gear '74, in mesh with a smaller gear 7 Son shaft29. Gear 75 is also in mesh with a gear 76 on a shaft 77 wh1ch also carres a pulley 78 over which a belt 79 is guided, also guided over a'pulley80 on a shaft 81. Double pulley 78 carries also a belt 82 guided over apulley 83 on a shaftBa, over this double pulley 83 also a belt 85 isguided running over a pullev 86 on the rear axle 12.

The motor is connected to a suitable source of electricity by meansof acable 87 adapted tobe wound upon a drum 88- on a vertical shaft 89journalled in a suitable bearing on a post 90, and a bearing 91 on box10.

The lower end of shaft 89 carries a bevel gear 92-in mesh with a bevelgear 93 on shaft 81, and a clutch 9a is adaptedto be operated by alever95.

A suitablebrake mechanism is provided, consisting of a brake wheel 96 onshaft 73 over which a band 97 is'guided having one of its ends attachedto the rear edge of beam 68 While its other end is secured to a loop 98carrying on its outer end a foot pedal 100.

Suitable clutch members101 are provided on shaft 99 and adapted to beshifted by a clutch shifter 102 while. a clutch 103 is shifted by meansof a shifter Shaft 73 carries also a pulley 105over which a belt 106 isguided which is also guided over a pulley 107 on shaft 4.0

The steering mechanism for the front wheels 15 on axle 14 comprises asteering rod 108 adapted to be operated bymeans. of a hand Wheel. 109 infront of the -driver s seat 16 and guided in suitable guides 110,

111. This rod carries at itsouter end a gear112 in mesh with a rack 113sliding in a suitable guide sleeve 11% on a frame bar 115. r

The inner end of bar 113 is pivotally atat 116, to a lever 117 ofthefront Snap-hook connections 121 or the like, are

provided at the 'upper,.front edge ofthe hopper 30 adapted to be engagedby similar connections 121 on the scoop 20 to hold the same securely in.its elevated position.

The shaft 36 of the stirrer is set exchangeab y in blocks or lugs 122having suitable depressions for the reception of the reduced ends of theshaft.

Below the drum 88, the shaft 89 thereof is equipped with a disc 123acting as a friction v brake forthe drumaud cable therein.

The apparatus operates as follows:

As soon as the motor is started to move the machine slowly forward, thescoop 20 will pick up the material and through the gears and belts, andits toothed segment will elevate the material and discharge it into thehopper 30 where it is stirred up to fall upon the endless belt conveys-rby which it is transferred onto the screen which will receive a shakingmotionby means of the eccentric link 58 on wheel .59. As soonlassufficient stones and rocks have accumulated in the screen, the rearendof the same is lowered to dump these stones and rocks which have notpassed through the screeninto the chute or shuttle 63 from which thematerial can readily be removed.

It will be understood that I may make such changes in the constructionof my apparatus as come within the scope of the appended claims withoutdeparture from the invention as disclosed.

Having thus described my invention, what I claim as new and desiretosecure by Letters Patent is i 1. Separator comprising a wheeled box,

means in said box to receive material, means in said receiving means tostir the material,

-means to scoop the material from the ground and to transfer it to saidmaterial receiving means, a screen, means to transport the ma terialfrom said receiving means to said screen, means for shakinggsaid screen,means for allowing a removalof the screen residue,

and a means for operatingall of said means from a common motor.
